Method Detail

getPreconditionType

public java.lang.String getPreconditionType()

Description copied from interface: SimplePrecondition

Gets the type of this precondition. Each sub-interface of Precondition has its own standard type identifier String. These identifier Strings are used instead of Java class names in order to ease portability of metadata to other languages.

Specified by:

getPreconditionType in interface Precondition

Specified by:

getPreconditionType in interface SimplePrecondition

Returns:

SimplePrecondition.PRECONDITION_TYPE

See Also:

Precondition.getPreconditionType()

getDefault

public boolean getDefault()

Description copied from interface: SimplePrecondition

Retrieves the default value for this precondition. This is the value returned if there is no applicable test value in the CAS.

Specified by:

getDefault in interface SimplePrecondition

Returns:

the default value

See Also:

SimplePrecondition.getDefault()

getFeatureName

public java.lang.String getFeatureName()

Description copied from interface: SimplePrecondition

Gets the name of the feature to be tested.

Specified by:

getFeatureName in interface SimplePrecondition

Returns:

the feature name, null if none

See Also:

SimplePrecondition.getFeatureName()

getFsIndexName

public java.lang.String getFsIndexName()

Description copied from interface: SimplePrecondition

Retrieves the name of the FeatureStructure index containing FeatureStructures to be tested by this precondition.

Specified by:

getFsIndexName in interface SimplePrecondition

Returns:

the name of the FS index, null if the default annotation index should be used

See Also:

SimplePrecondition.getFsIndexName()

getFsMatchConstraint

public FSMatchConstraint getFsMatchConstraint()

Description copied from interface: SimplePrecondition

Retrieves the FSMatchConstraint that determines which CAS feature structures will be tested by this precondition.

Specified by:

getFsMatchConstraint in interface SimplePrecondition

Returns:

the FS match constraint, null if none

See Also:

SimplePrecondition.getFsMatchConstraint()

setDefault

public void setDefault(boolean aDefault)

Description copied from interface: SimplePrecondition

Sets the default value for this precondition. This is the value returned if there is no applicable test value in the CAS.

Specified by:

setDefault in interface SimplePrecondition

Parameters:

aDefault - the default value

See Also:

SimplePrecondition.setDefault(boolean)

setFeatureName

public void setFeatureName(java.lang.String aFeatureName)

Description copied from interface: SimplePrecondition

Sets the name of the feature to be tested.

Specified by:

setFeatureName in interface SimplePrecondition

Parameters:

aFeatureName - the feature name, null if none

See Also:

SimplePrecondition.setFeatureName(java.lang.String)

setFsIndexName

public void setFsIndexName(java.lang.String aIndexName)

Description copied from interface: SimplePrecondition

Sets the name of the FeatureStructure index containing FeatureStructures to be tested by this precondition.

Specified by:

setFsIndexName in interface SimplePrecondition

Parameters:

aIndexName - the name of the FS index, null if the default annotation index should be used

See Also:

SimplePrecondition.setFsIndexName(java.lang.String)

setFsMatchConstraint

public void setFsMatchConstraint(FSMatchConstraint aConstraint)

Description copied from interface: SimplePrecondition

Sets the FSMatchConstraint that determines which CAS feature structures will be tested by this precondition.

Specified by:

setFsMatchConstraint in interface SimplePrecondition

Parameters:

aConstraint - the FS match constraint, null if none

See Also:

SimplePrecondition.setFsMatchConstraint(org.apache.uima.cas.FSMatchConstraint)

evaluate

public boolean evaluate(CAS aCAS)

Description copied from interface: Precondition

Determines if this precondition is satisfied by a CAS.

Specified by:

evaluate in interface Precondition

Parameters:

aCAS - the CAS against which to evaluate this precondition

Returns:

true if and only if the CAS satisfies this precondition.

See Also:

Precondition.evaluate(org.apache.uima.cas.CAS)

getComparisonValue

public java.lang.Object getComparisonValue()

Description copied from interface: SimplePrecondition
