Constructor Detail

FSLPath

public FSLPath()

Constructs an empty FSL path

FSLPath

public FSLPath(FSLLocationStep[] initialSteps)

Constructs an FSL path made of the location steps given as parameters

Method Detail

pathFactory

public static FSLPath pathFactory(java.lang.String fslPath,
                                  FSLNSResolver nsr,
                                  short firstStepType)

Instantiates a Java representation of the FSL path given as a String

Parameters:

fslPath - the FSL path, represented as a String

nsr - an FSLNSResolver containing namespace prefix binding declarations for all prefixes used in the path expression

firstStepType - one of FSLPath.NODE_STEP or FSLPath.ARC_STEP, depending on whether the first location step of the path expression should be interpreted as a node or arc location step

setNSResolver

public static void setNSResolver(FSLNSResolver nsr)

Set the namespace prefix binding table

splitQName

public static java.lang.String[] splitQName(java.lang.String qname)

Split a qualified name at the colon (e.g. dc:title -> {dc, title})

Parameters:

qname - the qualified name to split

appendLocationStep

public void appendLocationStep(FSLLocationStep ls)

append a location step to the path (the ordering of node vs. arc steps is not checked)

removeLastLocationStep

public void removeLastLocationStep()

remove last location step of the path

serialize

public java.lang.String serialize()

Serialize the path - get a String representation of this FSL path

Specified by:

serialize in class FSLExpression

toString

public java.lang.String toString()

Serialize the path - get a String representation of this FSL path

Overrides:

toString in class FSLExpression
