Constructor Detail

CodeReaderCache

public CodeReaderCache(int size)

Deprecated.

Creates a CodeReaderCache and sets the size of the CodeReaderCache in MB. Creating a new CodeReaderCache also adds an UpdateCodeReaderCacheListener to the workspace so that when a resource is changed then the CodeReader for that resource is removed from this cache.

Parameters:

size - initial size of the CodeReaderCache in terms of MB

Method Detail

finalize

protected void finalize()
                 throws Throwable

Deprecated.

Overrides:

finalize in class Object

Throws:

Throwable

get

public CodeReader get(String key)

Deprecated.

Get a CodeReader from the cache. The key is the char[] filename of the CodeReader to retrieve.

Specified by:

get in interface ICodeReaderCache

Parameters:

key - the path of the CodeReader to retrieve

Returns:

the CodeReader corresponding to the path specified by the key

get

public CodeReader get(String key,
                      IIndexFileLocation ifl)
               throws org.eclipse.core.runtime.CoreException,
                      IOException

Deprecated.

Description copied from interface: ICodeReaderCache

Retrieves the CodeReader corresponding to the key specified that represents the path for that CodeReader. If no CodeReader is found in the cache then a new CodeReader is created for the ifl and then returned.

Specified by:

get in interface ICodeReaderCache

Parameters:

key - the path corresponding to the CodeReader, generally: fileToParse.getLocation().toOSString()

Returns:

the CodeReader corresponding to the path specified by the key

Throws:

IOException

org.eclipse.core.runtime.CoreException

Since:

5.1

setCacheSize

public void setCacheSize(int size)

Deprecated.

Sets the max cache size of this cache in terms of MB.

Parameters:

size -

remove

public CodeReader remove(String key)

Deprecated.

Removes the CodeReader from the cache corresponding to the path specified by the key and returns the CodeReader that was removed. If no CodeReader is removed then null is returned.

Specified by:

remove in interface ICodeReaderCache

Parameters:

key -

Returns:

the removed CodeReader or null if not found

getCurrentSpace

public int getCurrentSpace()

Deprecated.

Returns the current size of the cache. For the CodeReaderCache this is in MB.

Specified by:

getCurrentSpace in interface ICodeReaderCache

flush

public void flush()

Deprecated.

Specified by:

flush in interface ICodeReaderCache
