- Method Detail
  - getXQView
```
XQStaticContext getXQView()
```
    Returns the XQStaticContext instance corresponding to this instance.
    
    Returns:
    
    the static context
  - getBindingTypeCheckMode
```
int getBindingTypeCheckMode()
```
    Gets the type checking mode for external variable bindings.
    
    Returns:
    
    the type checking mode, either OXQConstants.BINDING_TYPE_CHECK_MODE_PRIME or OXQConstants.BINDING_TYPE_CHECK_MODE_FULL
  - setBindingTypeCheckMode
```
void setBindingTypeCheckMode(int mode)
                      throws XQException
```
    Sets the type checking mode for external variable bindings. When set to OXQConstants.BINDING_TYPE_CHECK_MODE_PRIME, the XQuery processor assumes that the number of items bound to an external variable matches the type quantifier specified in the variable declaration and does not attempt to verify this assumption. By default, the processor will verify the type quantifier which can block streaming evaluation in some cases.
    
    For example, consider the following query:
    declare variable $arg as element(); $arg[1]
    
    Consider what happens if we bind (<a/>, <b/>) to this variable (a sequence of two elements). The binding mode is BINDING_TYPE_CHECK_MODE_FULL, this will result in a runtime error because "as element()" indicates there should be exactly 1 element bound to the variable. On the other hand, the binding mode is BINDING_TYPE_CHECK_MODE_PRIME, the XQuery processor will only ensure that the binding is an element but will not attempt to verify that there is exactly one element. The default value is OXQConstants.BINDING_TYPE_CHECK_MODE_FULL.
    
    Note, the relaxed type checking behavior used in mode BINDING_TYPE_CHECK_MODE_PRIME does not conform to the XQuery 1.0 standard.
    
    Parameters:
    
    mode - the type checking mode. Must be either OXQConstants.BINDING_TYPE_CHECK_MODE_PRIME or OXQConstants.BINDING_TYPE_CHECK_MODE_FULL
    
    Throws:
    
    XQException - the specified mode is different from OXQConstants.BINDING_TYPE_CHECK_MODE_PRIME or OXQConstants.BINDING_TYPE_CHECK_MODE_FULL
    
    See Also:
    
    getBindingTypeCheckMode()
  - getProcessingMode
```
int getProcessingMode()
```
    Gets the processing mode. In some cases, it may be useful to validate and analyze a query without any need to execute it. In such cases, the processing mode can be set to OXQConstants.PROCESSING_STATIC_ANALYSIS_ONLY to disable query optimization and plan generation. When in this mode, queries may not be executed. When the processing mode is OXQConstants.PROCESSING_FULL, queries may be prepared and executed. The default value is OXQConstants.PROCESSING_FULL.
    
    Returns:
    
    the processing mode. Must be either OXQConstants.PROCESSING_STATIC_ANALYSIS_ONLY or OXQConstants.PROCESSING_FULL
  - setProcessingMode
```
void setProcessingMode(int mode)
                throws XQException
```
    Sets the processing mode.
    
    Parameters:
    
    mode - the processing mode. Must be either OXQConstants.PROCESSING_STATIC_ANALYSIS_ONLY or OXQConstants.PROCESSING_FULL
    
    Throws:
    
    XQException - the specified mode is different from OXQConstants.PROCESSING_STATIC_ANALYSIS_ONLY or OXQConstants.PROCESSING_FULL
    
    See Also:
    
    getProcessingMode()
  - getModuleURI
```
java.lang.String getModuleURI()
```
    Gets the module URI, if set in the static context, else the empty string.
    
    Returns:
    
    the module URI, if set, else the empty string. Cannot be null
    
    See Also:
    
    setModuleURI(String)
  - setModuleURI
```
void setModuleURI(java.lang.String moduleUri)
           throws XQException
```
    Sets the module URI in the static context. If moduleUri is the empty string then the module URI setting will be cleared. The module URI will be used in error messages related to the main module. For example, by default a type error message in the main module might look something like the following:
    line 10, column 11: XPTY0004: Invalid static type ...
    If the module URI is set to "file:/myquery.xq", the error message would instead look something like:
    file:/myquery.xq, line 10, column 11: XPTY0004: Invalid static type ...
    
    Parameters:
    
    moduleUri - the new moduleUri, or the empty string to make it undefined. Cannot be null
    
    Throws:
    
    XQException - if a null module uri is specified, or given uri is not absolute
  - getEntityResolver
```
OXQEntityResolver getEntityResolver()
```
    Gets the OXQEntityResolver instance to be used during query processing.
    
    Returns:

```
    Sets an OXQEntityResolver instance to be used during query processing.
