Repository descriptors interface that is used to support providing the repository descriptors of javax.jcr.Repository

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`java.lang.String[]`	`getKeys()` Returns a string array holding all descriptor keys available for this implementation, both the standard descriptors defined by the string constants in this interface and any implementation-specific descriptors.
`Value`	`getValue(java.lang.String key)` The value of a single-value descriptor is found by passing the key for that descriptor to this method.
`Value[]`	`getValues(java.lang.String key)` The value array of a multi-value descriptor is found by passing the key for that descriptor to this method.
`boolean`	`isSingleValueDescriptor(java.lang.String key)` Returns `true` if `key` is a valid single-value descriptor; otherwise returns `false`
`boolean`	`isStandardDescriptor(java.lang.String key)` Returns `true` if `key` is a standard descriptor defined by the string constants in this interface and `false` if it is either a valid implementation-specific key or not a valid key.

- Method Detail
  - getKeys
```
java.lang.String[] getKeys()
```
    Returns a string array holding all descriptor keys available for this implementation, both the standard descriptors defined by the string constants in this interface and any implementation-specific descriptors. Used in conjunction with getValue(String key) and getValues(String key) to query information about this repository implementation.
    
    Returns:
    
    a string array holding all descriptor keys.
  - isStandardDescriptor
```
boolean isStandardDescriptor(java.lang.String key)
```
    Returns true if key is a standard descriptor defined by the string constants in this interface and false if it is either a valid implementation-specific key or not a valid key.
    
    Parameters:
    
    key - a descriptor key.
    
    Returns:
    
    whether key is a standard descriptor.
  - isSingleValueDescriptor
```
boolean isSingleValueDescriptor(java.lang.String key)
```
    Returns true if key is a valid single-value descriptor; otherwise returns false
    
    Parameters:
    
    key - a descriptor key.
    
    Returns:
    
    whether the specified descriptor is multi-valued.
    
    Since:
    
    JCR 2.0
  - getValue
```
Value getValue(java.lang.String key)
```
    The value of a single-value descriptor is found by passing the key for that descriptor to this method. If key is the key of a multi-value descriptor or not a valid key this method returns null.
    
    Parameters:
    
    key - a descriptor key.
    
    Returns:
    
    The value of the indicated descriptor
  - getValues
```
Value[] getValues(java.lang.String key)
```
    The value array of a multi-value descriptor is found by passing the key for that descriptor to this method. If key is the key of a single-value descriptor then this method returns that value as an array of size one. If key is not a valid key this method returns null.
    
    Parameters:
    
    key - a descriptor key.
    
    Returns:
    
    the value array for the indicated descriptor
