Method Detail

getSourceName

public String getSourceName()

Returns the URI, path or descriptive text indicating the origin of this script's source code.

setSourceName

public void setSourceName(String sourceName)

Sets the URI, path or descriptive text indicating the origin of this script's source code.

getRawSourceStart

public int getRawSourceStart()

Returns the start offset of the raw source. Only valid if getRawSource() returns non-null.

setRawSourceStart

Returns:

the raw source, or null if it was not recorded.

getBaseLineno

public int getBaseLineno()

setBaseLineno
