Function Documentation
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 @a ast parameter is a relation. The
RSL syntax supports the following relation operations:
<dl>
<dt>=</dt>
<dd>Equal</dd>
<dt>!=</dt>
<dd>Not Equal</dd>
<dt>></dt>
<dd>Greater Than</dd>
<dt>>=</dt>
<dd>Greater Than or Equal</dd>
<dt><</dt>
<dd>Less Than</dd>
<dt><=</dt>
<dd>Less Than or Equal</dd>
<dt><=</dt>
<dd>Less Than or Equal</dd>
</dl>
Some examples of RSL relations are
* "queue" = "debug"
* "queue" != "slow"
* "min_memory" > "1000"
* "max_wall_time" >= "60"
* "count < "10"
* "host_count" <= "5"
*
GRAM only supports equality relations.
Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_relation() function returns GLOBUS_TRUE if the RSL parse tree
pointed to by ast is a relation; otherwise, it returns GLOBUS_FALSE.
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 @a 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
* & ( "queue" = "debug") ( "max_time" = "10000")
* | ("count" = "1")("count" = "10")
* + ( &("executable" = "1.exe") ) ( & ("executable" = "2.exe" )
*
Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_boolean() function returns GLOBUS_TRUE if the RSL parse tree pointed
to by ast is a boolean composition; otherwise, it returns GLOBUS_FALSE.
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 @a ast parameter is an equality relation.
An example of an equality relation is
* "queue" = "debug"
*
Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_relation_eq() function returns GLOBUS_TRUE if the RSL parse tree
pointed to by ast is an equality relation; otherwise, it returns GLOBUS_FALSE.

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 @a ast parameter is a less-than relation.
An example of a less-than relation is
* "count" = "10"
*
Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_relation_lessthan() function returns GLOBUS_TRUE if the RSL parse
tree pointed to by ast is a less-than relation; otherwise, it returns GLOBUS_FALSE.

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 @a ast parameter is a relation with
the attribute name which matches the string pointed to by the
@a attribute parameter. This attribute name comparision is
case-insensitive.
Parameters:
ast Pointer to an RSL parse tree structure.
attribute Name of the attribute to test
Returns:
The globus_rsl_is_relation_attribute_equal() function returns GLOBUS_TRUE if the RSL
parse tree pointed to by ast is a relation and its attribute name matches the
attribute parameter; otherwise, it returns GLOBUS_FALSE.

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 @a ast parameter is a boolean "and"
composition of RSL trees.
An example of a boolean and relation is
* & ( "queue" = "debug" ) ( "executable" = "a.out" )
*
Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_boolean_and() function returns GLOBUS_TRUE if the RSL parse tree
pointed to by ast is a boolean and of RSL parse trees; otherwise, it returns
GLOBUS_FALSE.

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 @a ast parameter is a boolean "or" composition
of RSL trees.
An example of a boolean or relation is
* | ( "count" = "2" ) ( "count" = "4" )
*
Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_boolean_or() function returns GLOBUS_TRUE if the RSL parse tree
pointed to by ast is a boolean and of RSL parse trees; otherwise, it returns
GLOBUS_FALSE.
