FastParser.StructRef
public FastParser.StructRef(FastParser.StructRef theParent,
java.lang.String theRelativePath,
boolean isSegment,
int[] theFields)
- Parameters:
theParent
- a StructRef for the parent Group of the referenced StructuretheRelativePath
- the relative (from the parent) Terser path to the referenced
structure. If the structure repeats, the rep number should be replaced with "*"
(it will be incremented as needed).isSegment
- true iff the referenced Structure is a Segment (rather than a Group)theFields
- a list of fields to be parsed for this segment (null or empty for groups)
setSuccessor
public void setSuccessor(java.lang.String theName,
FastParser.StructRef theSuccessor)
- Indicates an immediately subsequent structure in parsing order. A Structure in a list
should point to the next Structure in the list. A Structure that repeats should point to
itself. A Structure at the end of a repeating Group should point to the Group.
A Group should point to its first child.
- Parameters:
theName
- name of the next Segment in this direction (ie if the next structure is a group,
not that one)theSuccessor
- the immediately next StructRef in that direction
getFullPath
public java.lang.String getFullPath()
- Returns:
- full Terser path, including parent and repetition information.
getRelativePath
public java.lang.String getRelativePath()
- Returns:
- relative Terser path as defined in constructor
getSuccessor
public FastParser.StructRef getSuccessor(java.lang.String theName)
- Parameters:
theName
- name of a successor in parse order, as set in setSuccessor()
- Returns:
- the StructRef under that name
getChildName
public java.lang.String getChildName()
- Returns:
- name of first successor, if available and if this is not a segment reference,
otherwise null
isSegment
public boolean isSegment()
- Returns:
- true iff referenced Structure is a Segment
reset
public void reset()
- Resets the StructRef to its starting state, before its first iteration, and resets
its children as well.
getFields
public int[] getFields()
- Returns:
- an ordered list of fields to be parsed for this segment (empty if not a segment)
