Class SourceOrigin

java.lang.Object

com.google.gwt.dev.jjs.SourceOrigin

All Implemented Interfaces:

SourceInfo, Serializable

public class SourceOrigin
extends Object
implements SourceInfo

Describes where a SourceInfo's node came from. This class currently includes only physical origin information, but could be extended to provide support for source-Module and -Generators. TODO: rename this class to make it parallel to SourceInfoCorrelation? TODO: make this package-protected?

Method Detail

create

public static SourceOrigin create(int startPos,
                                  int endPos,
                                  int startLine,
                                  String fileName)

Creates SourceOrigin nodes.

create

public static SourceOrigin create(int startLine,
                                  String fileName)

Creates SourceOrigin nodes. This factory method will attempt to provide canonicalized instances of SourceOrigin objects.

addCorrelation

public void addCorrelation(Correlation c)

Description copied from interface: SourceInfo

Add a Correlation to the SourceInfo.

Specified by:

addCorrelation in interface SourceInfo

equals

public boolean equals(Object o)

Overrides:

equals in class Object

getCorrelation

public Correlation getCorrelation(Correlation.Axis axis)

Description copied from interface: SourceInfo

Return the Correlation that has been set for a given Axis, or null if no Correlation has been set on the given axis.

Specified by:

getCorrelation in interface SourceInfo

getCorrelations

public Correlation[] getCorrelations()

Description copied from interface: SourceInfo

Returns the Correlations added along each Axis on which a Correlation has been set. Some entries may be null and should be ignored.

Specified by:

getCorrelations in interface SourceInfo

getCorrelator

public CorrelationFactory getCorrelator()

Description copied from interface: SourceInfo

Returns the correlation factory that created this node.

Specified by:

getCorrelator in interface SourceInfo

getEndPos

public int getEndPos()

Specified by:

getEndPos in interface SourceInfo

getFileName

public String getFileName()

Specified by:

getFileName in interface SourceInfo

makeChild

public SourceInfo makeChild()

Description copied from interface: SourceInfo

Create a child node of the same type and Origin as this node. If data accumulation is enabled, the derived node will inherit its Correlations from this node.

Specified by:

makeChild in interface SourceInfo

makeChild

public SourceInfo makeChild(SourceOrigin origin)

Description copied from interface: SourceInfo

Specified by:

makeChild in interface SourceInfo

toString
