Constructor Detail

SimpleTag

public SimpleTag(java.lang.String v,
                 ExprTag[] t)

Creates a new SimpleTag from a string and an array of tags.

Parameters:

v - type of this SimpleTag.

t - sequence of tags.

Method Detail

intersect

public Tag intersect(Tag that)

If that is a SimpleTag, returns intersect((SimpleTag)that). If that is a SetTag, returns that.intersect(this). Otherwise returns NULL_TAG.

Specified by:

intersect in class Tag

Parameters:

that - tag to intersect this with.

Returns:

the intersection of this Tag and that.

See Also:

Tag.intersect(Tag)

intersect

public Tag intersect(SimpleTag that)

If that has the same value as this, intersect returns a new SimpleTag as long as the longer of the two tags whose elements are the intersection of the corresponding elements. Elements past the end of the shorter tag are copied from the longer tag. If any of the intersections is not an ExprTag, or if that is not a SimpleTag, or if that's value differs from this's value, intersect returns NULL_TAG.

equals

public boolean equals(java.lang.Object that)

Specified by:

equals in class Obj

Object.equals(Object)

hashCode

public int hashCode()

Specified by:

hashCode in class Obj

See Also:

Object.hashCode()

getValue

public java.lang.String getValue()

Returns:

the string value of this SimpleTag.

getTags

public ExprTag[] getTags()

Returns:

the tags of this SimpleTag.

toTagSexp

public Sexp toTagSexp()

Specified by:

toTagSexp in class Tag
