Method Detail

getCanonicalForm

public java.lang.String getCanonicalForm()

Description copied from interface: PathElement

Get the canonical form of this PathElement. Really only interesting for the Reference Path element, where it will expand "&" to "&0(0)".

Specified by:

getCanonicalForm in interface PathElement

Returns:

canonical String version of this PathElement

evaluate

public java.lang.String evaluate(WalkedPath walkedPath)

Description copied from interface: EvaluatablePathElement

Evaluate this key as if it is an write path element.

Specified by:

evaluate in interface EvaluatablePathElement

Parameters:

walkedPath - "up the tree" list of LiteralPathElements, that may be used by this key as it is computing

Returns:

String path element to use for write tree building

verifyStringIsNonNegativeInteger

private static java.lang.String verifyStringIsNonNegativeInteger(java.lang.String key)

Returns:

the String version of a non-Negative integer, else null

getExplicitArrayIndex

public java.lang.Integer getExplicitArrayIndex()

isExplicitArrayIndex

public boolean isExplicitArrayIndex()

match

public MatchedElement match(java.lang.String dataKey,
                            WalkedPath walkedPath)

Description copied from interface: MatchablePathElement

See if this PathElement matches the given dataKey. If it does not match, this method returns null. If this PathElement does match, it returns a LiteralPathElement with subKeys filled in.

Specified by:

match in interface MatchablePathElement

Parameters:

dataKey - String key value from the input data

walkedPath - "up the tree" list of LiteralPathElements, that may be used by this key as it is computing its match

Returns:

null or a matched LiteralPathElement
