RSL Predicates.
The functions in this group return boolean values indicating whether an RSL syntax tree is of a particular type.
int globus_rsl_is_boolean | ( | globus_rsl_t * | ast | ) |
RSL boolean test.
The globus_rsl_is_boolean() function tests whether the the RSL pointed to by the ast parameter is a boolean composition of other RSL parse trees. The syntactically understood boolean compositions are "&" (conjunction), "|" (disjunction), and "+" (multi-request). Some bexamples of RSL booleans are
ast | Pointer to an RSL parse tree structure. |
int globus_rsl_is_boolean_and | ( | globus_rsl_t * | ast | ) |
RSL boolean and test.
The globus_rsl_is_boolean_and() function tests whether the the RSL pointed to by the ast parameter is a boolean "and" composition of RSL trees.
An example of a boolean and relation is
ast | Pointer to an RSL parse tree structure. |
int globus_rsl_is_boolean_multi | ( | globus_rsl_t * | ast | ) |
RSL boolean multi test.
The globus_rsl_is_boolean_multi() function tests whether the the RSL pointed to by the ast parameter is a boolean "multi-request" composition of RSL trees.
An example of a boolean multie-request relation is
ast | Pointer to an RSL parse tree structure. |
int globus_rsl_is_boolean_or | ( | globus_rsl_t * | ast | ) |
RSL boolean or test.
The globus_rsl_is_boolean_or() function tests whether the the RSL pointed to by the ast parameter is a boolean "or" composition of RSL trees.
An example of a boolean or relation is
ast | Pointer to an RSL parse tree structure. |
int globus_rsl_is_relation | ( | globus_rsl_t * | ast | ) |
RSL relation test.
The globus_rsl_is_relation() function tests whether the the RSL pointed to by the ast parameter is a relation. The RSL syntax supports the following relation operations:
Some examples of RSL relations are
ast | Pointer to an RSL parse tree structure. |
int globus_rsl_is_relation_attribute_equal | ( | globus_rsl_t * | ast, |
char * | attribute | ||
) |
RSL attribute name test.
The globus_rsl_is_relation_attribute_equal() function tests whether the the RSL pointed to by the ast parameter is a relation with the attribute name which matches the string pointed to by the attribute parameter. This attribute name comparison is case-insensitive.
ast | Pointer to an RSL parse tree structure. |
attribute | Name of the attribute to test |
int globus_rsl_is_relation_eq | ( | globus_rsl_t * | ast | ) |
RSL equality operation test.
The globus_rsl_is_relation_eq() function tests whether the the RSL pointed to by the ast parameter is an equality relation. An example of an equality relation is
ast | Pointer to an RSL parse tree structure. |
int globus_rsl_is_relation_lessthan | ( | globus_rsl_t * | ast | ) |
RSL less than operation test.
The globus_rsl_is_relation_lessthan() function tests whether the the RSL pointed to by the ast parameter is a less-than relation. An example of a less-than relation is
ast | Pointer to an RSL parse tree structure. |
int globus_rsl_value_is_concatenation | ( | globus_rsl_value_t * | ast | ) |
RSL value concatenation test.
The globus_rsl_value_is_concatenation() function tests whether the the RSL value pointed to by the ast parameter is a concatenation of RSL values. An example of an RSL value concatenation is
ast | Pointer to an RSL value structure. |
int globus_rsl_value_is_literal | ( | globus_rsl_value_t * | ast | ) |
RSL literal string test.
The globus_rsl_value_is_literal() function tests whether the the RSL value pointed to by the ast parameter is a literal string value.
An example of a literal string is
ast | Pointer to an RSL value structure. |
int globus_rsl_value_is_sequence | ( | globus_rsl_value_t * | ast | ) |
RSL value sequence test.
The globus_rsl_value_is_sequence() function tests whether the the RSL value pointed to by the ast parameter is a sequence of RSL values. An example of a sequence of values is
ast | Pointer to an RSL value structure. |
int globus_rsl_value_is_variable | ( | globus_rsl_value_t * | ast | ) |
RSL value variable test.
The globus_rsl_value_is_variable() function tests whether the the RSL value pointed to by the ast parameter is a variable reference. RSL values. An example of a variable reference is
ast | Pointer to an RSL value structure. |
