Field Details

isFragment

private final int isFragment

If Element.offset must be fixed to a value, the bitwise NOT value of that offset. Otherwise 0. This field packs two information:

• Element.isFragment = (isFragment != 0)
• If isFragment is true, then:
  • Element.offset = ~isFragment

offsets

private final short[] offsets

The StoredTree.offsets array. Shall not be modified because potentially shared. Ignored if isFragment != 0.

index

private int index

Index of the next offset to return in the offsets array. Ignored if isFragment != 0.

errorLocale

final Locale errorLocale

Locale to use for producing error message.

Constructor Details

Inflater

Inflater(AbstractParser parser,
 short[] offsets,
 int isFragment)

Creates a new inflater.

Parameters:

parser - the parser which will be used for parsing the tree.

offsets - the StoredTree.offsets array. Will not be modified.

isFragment - non-zero if and only if Element.isFragment is true. In such case, this value must be ~Element.offset.

Method Details

nextOffset

final int nextOffset()

Returns the value to assign to Element.offset for the next element.
