Method Detail

canContain

public boolean canContain(int parent,
                          int child)

True if parent can directly contain child.

indexForName

public int indexForName(String canonName)

The element index for the element with the given name.

canonNameForIndex

public String canonNameForIndex(int index)

The element index for the element with the given name.

resumable

public boolean resumable(int index)

The elements that can be resumed after misnested inline tags.

canContainText

public boolean canContainText(int index)

Whether parsing can produce an element with the given index that contains a text node.

canContainPlainText

public boolean canContainPlainText(int index)

Whether parsing can produce an element with the given index that contains a text node that has human readable text instead of script or style source code.

nElementTypes

public int nElementTypes()

The number of element types which is also the exclusive upper bound on element indices.

unpack

public static boolean[] unpack(int[] packed,
                               int length)

Unpacks a boolean[] from an array of ints. This allows us to store largish boolean[]s in relatively small numbers of bytecode instructions.
