Class XMLSchemaValidator.ValueStoreCache

    java.lang.Object
      org.apache.xerces.impl.xs.XMLSchemaValidator.ValueStoreCache

Enclosing class:
  XMLSchemaValidator

    protected class XMLSchemaValidator.ValueStoreCache

extends java.lang.Object

Value store cache. This class is used to store the values for identity constraints.

Author:
  Andy Clark, IBM

Field Summary
`protected java.util.HashMap` | `fGlobalIDConstraintMap`
`protected java.util.Stack` | `fGlobalMapStack`
`protected java.util.HashMap` | `fIdentityConstraint2ValueStoreMap` Values stores associated to specific identity constraints.
`protected java.util.ArrayList` | `fValueStores` stores all global Values stores.

Constructor Summary
`XMLSchemaValidator.ValueStoreCache()` Default constructor.

Method Summary
`void` | `endDocument()` Check identity constraints.
`void` | `endElement()` endElement(): merges contents of fGlobalIDConstraintMap with the top of fGlobalMapStack into fGlobalIDConstraintMap.
`XMLSchemaValidator.ValueStoreBase` | `getGlobalValueStoreFor(IdentityConstraint id)` Returns the global value store associated to the specified IdentityConstraint.
`XMLSchemaValidator.ValueStoreBase` | `getValueStoreFor(IdentityConstraint id, int initialDepth)` Returns the value store associated to the specified IdentityConstraint.
`void` | `initValueStoresFor(XSElementDecl eDecl, FieldActivator activator)` Initializes the value stores for the specified element declaration.
`void` | `startDocument()` Resets the identity constraint cache.
`void` | `startElement()`
`java.lang.String` | `toString()` Returns a string representation of this object.
`void` | `transplant(IdentityConstraint id, int initialDepth)`

Field Detail

### fValueStores

    protected final java.util.ArrayList fValueStores

  stores all global Values stores.

### fIdentityConstraint2ValueStoreMap

    protected final java.util.HashMap fIdentityConstraint2ValueStoreMap

  Values stores associated to specific identity constraints. This hashtable maps IdentityConstraints and the 0-based element on which their selectors first matched to a corresponding ValueStore. This should take care of all cases, including where ID constraints with descendant-or-self axes occur on recursively-defined elements.

### fGlobalMapStack

    protected final java.util.Stack fGlobalMapStack

### fGlobalIDConstraintMap

    protected final java.util.HashMap fGlobalIDConstraintMap

Constructor Detail

### XMLSchemaValidator.ValueStoreCache

    public XMLSchemaValidator.ValueStoreCache()

  Default constructor.

Method Detail

### startDocument

    public void startDocument()

  Resets the identity constraint cache.

### startElement

    public void startElement()

### endElement

    public void endElement()

  endElement(): merges contents of fGlobalIDConstraintMap with the top of fGlobalMapStack into fGlobalIDConstraintMap.

### initValueStoresFor

    public void initValueStoresFor(XSElementDecl eDecl,
                                   FieldActivator activator)

  Initializes the value stores for the specified element declaration.

### getValueStoreFor

    public XMLSchemaValidator.ValueStoreBase getValueStoreFor(IdentityConstraint id,
                                                              int initialDepth)

  Returns the value store associated to the specified IdentityConstraint.

### getGlobalValueStoreFor

    public XMLSchemaValidator.ValueStoreBase getGlobalValueStoreFor(IdentityConstraint id)

  Returns the global value store associated to the specified IdentityConstraint.

### transplant

    public void transplant(IdentityConstraint id,
                           int initialDepth)

### endDocument

    public void endDocument()

  Check identity constraints.

### toString

    public java.lang.String toString()

  Returns a string representation of this object.

  Overrides:
    `toString` in class `java.lang.Object`
