All known Subclasses: org.jpox.store.query.AbstractJPQLQuery, org.jpox.store.query.AbstractJDOQLQuery,
| AbstractJavaQuery | | abstract public class AbstractJavaQuery extends Query (Code) | | Abstract representation of a Java-based query.
To be extended by Java-based query languages.
version:
$Revision$ |
| Inner Class :public static class ExecutedCompileCache | |
| candidateCollection | | protected transient Collection candidateCollection(Code) | | Collection of candidates for this query.
|
| candidateExtent | | protected transient Extent candidateExtent(Code) | | Extent of candidates for this query.
|
| candidates | | protected transient Queryable candidates(Code) | | Candidates for this query.
|
| compiledCache | | protected static Map compiledCache(Code) | | Some cache of compiled queries that is never used currently.
|
| distinct | | protected transient boolean distinct(Code) | | whether to apply "distinct" results. *
|
| resultMetaData | | protected transient JPOXResultSetMetaData resultMetaData(Code) | | Result metadata (JPOX extension, allowing access to more info). *
|
| singleString | | protected String singleString(Code) | | Cached form of the single string form of the query.
|
| userDefinedScalarExpressions | | protected static transient Map userDefinedScalarExpressions(Code) | | Register of user-defined ScalarExpression, provided via plugins.
|
| AbstractJavaQuery | | public AbstractJavaQuery(ObjectManager om)(Code) | | Constructor for a Java-based query.
Parameters:
om - The ObjectManager |
| getCachedQuery | | protected ExecutedCompileCache getCachedQuery()(Code) | | Accessor for a compiled form of this query in the cache (if present).
Compiled form of this query if currently cached. |
| getCandidateCollection | | public Collection getCandidateCollection()(Code) | | Accessor for the candidate collection (if specified using a collection).
Candidate collection |
| getCandidateExtent | | public Extent getCandidateExtent()(Code) | | Accessor for the candidate Extent (if specified using an Extent).
Candidate Extent |
| getCandidates | | public Queryable getCandidates()(Code) | | Accessor for the candidates for the query.
This is only valid after compiling the query.
Candidates for the query |
| getParsedImports | | protected Imports getParsedImports()(Code) | | Accessor for the parsed imports.
If no imports are set then adds candidate class, user imports, and any user-defined expression packages.
Parsed imports |
| getResultSetMetaData | | public JPOXResultSetMetaData getResultSetMetaData()(Code) | | Retrieve the metadata for the results
the ResultSetMetaData |
| getSingleStringQuery | | abstract public String getSingleStringQuery()(Code) | | Accessor for a single string form of the query.
Single string form of the query. |
| getUserDefinedScalarExpressions | | public static Map getUserDefinedScalarExpressions()(Code) | | Accessor for the user-defined scalar expressions.
Map of user-defined scalar expressions |
| registerScalarExpression | | public static void registerScalarExpression(Class literal, Class scalarExpressionClass, String name)(Code) | | Register ScalarExpressions for the given cls. It allows
to perform operations in the query on cls.method([arglist]).
Parameters:
literal - the class providing the operations; e.g. java.lang.Math.class
Parameters:
scalarExpressionClass - the class with the corresponding ScalarExpression. eg. org.jpox.store.expression.MathExpression.class
Parameters:
name - alternative name of the given literal class |
| registerScalarExpressions | | protected void registerScalarExpressions(PluginManager pluginMgr, ClassLoaderResolver clr)(Code) | | Register ScalarExpression classes delcared as plug-ins extensions
TODO currently register only the first time this class is instantiated. Should be registered per PMF?
Parameters:
pluginMgr - The PluginManager
Parameters:
clr - The ClassLoaderResolver to load the literal and ScalarExpression classes |
| resultHasOnlyAggregates | | public boolean resultHasOnlyAggregates(String result)(Code) | | Convenience method to simple-parse the "result" clause returning if it includes
solely aggregates. This is necessary since we need this information before creating the
QueryStatement, after which we compile the result.
Parameters:
result - The result required Whether it has only aggregates |
| setCandidates | | public void setCandidates(Extent pcs)(Code) | | Set the candidate Extent to query.
Parameters:
pcs - the Candidate Extent.
See Also: javax.jdo.Query.setCandidates(javax.jdo.Extent) |
| setCandidates | | public void setCandidates(Collection pcs)(Code) | | Set the candidate Collection to query.
Parameters:
pcs - the Candidate collection.
See Also: javax.jdo.Query.setCandidates(java.util.Collection) |
| toString | | public String toString()(Code) | | Stringifier method
Single-string form of this JDOQL query. |
