Method Detail

addIfMatch

public void addIfMatch(Tag tag)

Adds tags to the If-Match header.

Parameters:

tag - the tag to add, may be null. This means the same as adding Tag.ALL

Throws:

java.lang.IllegalArgumentException - if ALL is supplied more than once, or you add a null tag more than once.

addIfNoneMatch

public void addIfNoneMatch(Tag tag)

Adds tags to the If-None-Match header. The meaning of "If-None-Match: *" is that the method MUST NOT be performed if the representation selected by the origin server (or by a cache, possibly using the Vary mechanism, see section 14.44) exists, and SHOULD be performed if the representation does not exist. FThis feature is intended to be useful in preventing races between PUT operations.

Parameters:

tag - the tag to add, may be null. This means the same as adding Tag.ALL

Throws:

java.lang.IllegalArgumentException - if ALL is supplied more than once, or you add a null tag more than once.

public void setIfModifiedSince(org.joda.time.DateTime time)

You should use the server's time here. Otherwise you might get unexpected results.

Parameters:

setIfUnModifiedSince

public void setIfUnModifiedSince(org.joda.time.DateTime time)

You should use the server's time here. Otherwise you might get unexpected results.
