Class RefSpec

java.lang.Object
  org.eclipse.jgit.transport.RefSpec

All Implemented Interfaces:

Serializable

public class RefSpec
extends Object
implements Serializable

Describes how refs in one repository copy into another repository.

A ref specification provides matching support and limited rules to rewrite a reference in one repository to another reference in another repository.

WILDCARD_SUFFIX

Suffix for wildcard ref spec component, that indicate matching all refs with specified prefix.

Constant Field Values

Constructor Detail

RefSpec

public RefSpec()

Construct an empty RefSpec.

A newly created empty RefSpec is not suitable for use in most applications, as at least one field must be set to match a source name.

RefSpec

public RefSpec(String spec)

Parse a ref specification for use during transport operations.

Specifications are typically one of the following forms:

• refs/head/master
• refs/head/master:refs/remotes/origin/master
• refs/head/*:refs/remotes/origin/*
• +refs/head/master
• +refs/head/master:refs/remotes/origin/master
• +refs/head/*:refs/remotes/origin/*
• :refs/head/master

Parameters:

spec - string describing the specification.

Throws:

IllegalArgumentException - the specification is invalid.

Method Detail

isWildcard

public static boolean isWildcard(String s)

Check whether provided string is a wildcard ref spec component.

Parameters:

s - ref spec component - string to test. Can be null.

Returns:

true if provided string is a wildcard ref spec component.

isForceUpdate

public boolean isForceUpdate()

Check if this specification wants to forcefully update the destination.

Returns:

true if this specification asks for updates without merge tests.

setForceUpdate

public RefSpec setForceUpdate(boolean forceUpdate)

Create a new RefSpec with a different force update setting.

Parameters:

forceUpdate - new value for force update in the returned instance.

Returns:

a new RefSpec with force update as specified.

isWildcard

public boolean isWildcard()

Check if this specification is actually a wildcard pattern.

If this is a wildcard pattern then the source and destination names returned by getSource() and getDestination() will not be actual ref names, but instead will be patterns.

Returns:

true if this specification could match more than one ref.

getSource

public String getSource()

Get the source ref description.

During a fetch this is the name of the ref on the remote repository we are fetching from. During a push this is the name of the ref on the local repository we are pushing out from.

Returns:

name (or wildcard pattern) to match the source ref.

setSource

public RefSpec setSource(String source)

Create a new RefSpec with a different source name setting.

Parameters:

source - new value for source in the returned instance.

Returns:

a new RefSpec with source as specified.

Throws:

IllegalStateException - There is already a destination configured, and the wildcard status of the existing destination disagrees with the wildcard status of the new source.

getDestination

public String getDestination()

Get the destination ref description.

During a fetch this is the local tracking branch that will be updated with the new ObjectId after fetching is complete. During a push this is the remote ref that will be updated by the remote's receive-pack process.

If null during a fetch no tracking branch should be updated and the ObjectId should be stored transiently in order to prepare a merge.

If null during a push, use getSource() instead.

Returns:

name (or wildcard) pattern to match the destination ref.

setDestination

public RefSpec setDestination(String destination)

Create a new RefSpec with a different destination name setting.

Parameters:

destination - new value for destination in the returned instance.

Returns:

a new RefSpec with destination as specified.

Throws:

IllegalStateException - There is already a source configured, and the wildcard status of the existing source disagrees with the wildcard status of the new destination.

setSourceDestination

public RefSpec setSourceDestination(String source,
                                    String destination)

Create a new RefSpec with a different source/destination name setting.

Parameters:

source - new value for source in the returned instance.

destination - new value for destination in the returned instance.

Returns:

a new RefSpec with destination as specified.

Throws:

IllegalArgumentException - The wildcard status of the new source disagrees with the wildcard status of the new destination.

matchSource

public boolean matchSource(String r)

Does this specification's source description match the ref name?

Parameters:

r - ref name that should be tested.

Returns:

true if the names match; false otherwise.

matchSource

public boolean matchSource(Ref r)

Does this specification's source description match the ref?

Parameters:

r - ref whose name should be tested.

Returns:

true if the names match; false otherwise.

matchDestination

public boolean matchDestination(String r)

Does this specification's destination description match the ref name?

Parameters:

r - ref name that should be tested.

Returns:

true if the names match; false otherwise.

matchDestination

public boolean matchDestination(Ref r)

Does this specification's destination description match the ref?

Parameters:

r - ref whose name should be tested.

Returns:

true if the names match; false otherwise.

expandFromSource

public RefSpec expandFromSource(String r)

Expand this specification to exactly match a ref name.

Callers must first verify the passed ref name matches this specification, otherwise expansion results may be unpredictable.

Parameters:

r - a ref name that matched our source specification. Could be a wildcard also.

Returns:

a new specification expanded from provided ref name. Result specification is wildcard if and only if provided ref name is wildcard.

expandFromSource

public RefSpec expandFromSource(Ref r)

Expand this specification to exactly match a ref.

Callers must first verify the passed ref matches this specification, otherwise expansion results may be unpredictable.

Parameters:

r - a ref that matched our source specification. Could be a wildcard also.

Returns:

a new specification expanded from provided ref name. Result specification is wildcard if and only if provided ref name is wildcard.

expandFromDestination

public RefSpec expandFromDestination(String r)

Expand this specification to exactly match a ref name.

Callers must first verify the passed ref name matches this specification, otherwise expansion results may be unpredictable.

Parameters:

r - a ref name that matched our destination specification. Could be a wildcard also.

Returns:

a new specification expanded from provided ref name. Result specification is wildcard if and only if provided ref name is wildcard.

expandFromDestination

public RefSpec expandFromDestination(Ref r)

Expand this specification to exactly match a ref.

Callers must first verify the passed ref matches this specification, otherwise expansion results may be unpredictable.

Parameters:

r - a ref that matched our destination specification.

Returns:

a new specification expanded from provided ref name. Result specification is wildcard if and only if provided ref name is wildcard.
