Constructor Detail

DefaultInlineMap

public DefaultInlineMap()

Creates a DefaultInlineMap. Doesn't need any arguments to the constructor, because it is very stupid.

Method Detail

canInline1

public boolean canInline1(HField hf)

Specified by:

canInline1 in class InlineMap

Returns:

true if the HField can be inlined using type 1 inlining (the class descriptor for the inlined object is preserved). This can be done even if the field escapes, as long as it is a final field.

canInline2

public boolean canInline2(HField hf)

Specified by:

canInline2 in class InlineMap

Returns:

true if the HField should be inlined using type 2 inlining (the class descriptor for the inlined object is omitted). This can only be done if the field doesn't escape. Returning true implies shouldInline1() returns true, too.
