Interface IFilterMetadataAssertion

All Superinterfaces:

IFilterAssertion

public interface IFilterMetadataAssertion

extends IFilterAssertion

Represents a filter assertion about metadata.
This assertion is made up of a comparator (operator), metadataID and assertion value.

// * The particular type and form of the IMetadata used as an assertion is dictated by the comparator and the metadata type. // * In other words, a particular attribute type will specify the comparators valid for that type, as well as the format of assertion value for each valid comparator. TODO (Doc): Refer to example specifications for this

Field Summary

static String	COMP_META_EQ Compares true when a tested Entity has a metadata of the specified type which contains a value equal to the specified assertion value.
static String	COMP_META_PRESENT Compares true when the specified metadata type is present in a tested container of metadata.
static String	COMP_PROP_GE Compares true when a tested Entity has a metadata of the specified type which contains a value greater or equal to the specified assertion value.
static String	COMP_PROP_LE Compares true when a tested Entity has a metadata of the specified type which contains a value less or equal to the specified assertion value.
static String	COMP_PROP_SUBSTR Compares true when a tested Entity has a metadata of the specified type which contains a value containing the substring specified by the assertion value.

Method Summary

void	setAssertionValue(IMetadata assertion) Specifies the assertion data to be tested against values of a metadata container's metadata.
