| QueryCompiler | | public QueryCompiler(Query query, Imports imports, Map parameters)(Code) | | Constructor for a compiler of java queries.
Parameters:
query - The query to compile
Parameters:
imports - The imports to use
Parameters:
parameters - Any parameters |
| close | | public void close()(Code) | | Method to close the Compiler.
|
| compile | | public Object compile(int type)(Code) | | Method to compile the query.
Parameters:
type - Type of compilation. This compiler only supports explicit parameters, explicit variables the compilation artifact (if any) |
| compileExplicitParameters | | protected void compileExplicitParameters()(Code) | | Method to compile all parameters declared for this query.
Takes the input "parameters" and populates "parameterNames", "parameterTypesByName" for convenience.
|
| compileExplicitVariables | | protected void compileExplicitVariables()(Code) | | Method to compile all variables declared for this query.
Takes the input "variables" and populates "variableNames", "variableTypesByName" for convenience.
|
| getCandidateAlias | | public String getCandidateAlias()(Code) | | Accessor for the candidate alias.
Candidate alias |
| getCandidateClass | | public Class getCandidateClass()(Code) | | Accessor for the candidate class. May have been updated during the compile process.
Candidate class |
| getParameterNames | | public String[] getParameterNames()(Code) | | Accessor for the (explicit) parameter names.
Parameter names |
| getParameterTypesByName | | public Map getParameterTypesByName()(Code) | | Accessor for the parameter types keyed by the parameter name.
Generated during compile of explicit parameters.
Map of parameter type keyed by name |
