allResourceSelector

public static <T extends ContentMeta> ResourceSelector<T> allResourceSelector()

A resource selector which always matches

Type Parameters:

T - content type

Returns:

selector

resourceSelector

public static <T extends ContentMeta> ResourceSelector<T> resourceSelector(java.lang.String selector)

Return a ResourceSelector constructed using this selector syntax:

 key OP value [; key OP value]*
 

OP can be "=" (exact match) or "=~" (regular expression match).
The returned selector effectively "AND"s the match requirements.
The special string "*" equates to allResourceSelector()

Type Parameters:

T - resource type

Parameters:

selector - the selector syntax string to parse, not null

Returns:

a resource selector corresponding to the parsed selector string
