- Method Detail
  - empty
```
public static ContextPattern empty()
```
    Create an empty context pattern.
    
    Returns:
    
    A context pattern matching only the empty context.
  - any
```
public static ContextPattern any()
```
    Create a context pattern matching any context.
    
    Returns:
    
    A context pattern matching any context.
  - subsequence
```
public static ContextPattern subsequence(Class<?>... types)
```
    Create a context matcher matching any context with the specified subsequence.
    
    Parameters:
    
    types - The subsequence to match.
    
    Returns:
    
    A context matcher that matches any context of which types (with the default qualifier matchers) is a subsequence.
  - subsequence
```
public static ContextPattern subsequence(ContextElementMatcher... matchers)
```
    Create a context matcher matching any context with a subequence matching the provided matchers.
    
    Parameters:
    
    matchers - The matchers to match a subsequence.
    
    Returns:
    
    A context matcher that matches any context of which types (with the default qualifier matchers) is a subsequence.
  - append
```
public ContextPattern append(ContextElementMatcher match,
                             Multiplicity mult)
```
    Append an element to this pattern. The pattern is not modified; rather, a new pattern extended with the new matching element is returned.
    
    Parameters:
    
    match - The element matcher.
    
    mult - The multiplicity of this element.
    
    Returns:
    
    This pattern extended by the new element.
  - append
```
public ContextPattern append(ContextElementMatcher match)
```
    Append an element to this pattern with multiplicity Multiplicity.ONE.
    
    Parameters:
    
    match - The element matcher.
    
    Returns:
    
    This pattern extended by the new element.
  - append
```
public ContextPattern append(Class<?> type)
```
    Append a type element to this pattern with multiplicity Multiplicity.ONE.
    
    Parameters:
    
    type - The type to match, passed to ContextElements.matchType(Class).
    
    Returns:
    
    This pattern extended by the new element.
  - append
```
public ContextPattern append(ContextPattern toAppend)
```
    Append a context pattern to this pattern.
    
    Parameters:
    
    toAppend - The pattern to append.
    
    Returns:
    
    The concatenation of this pattern and toAppend.
  - appendDotStar
```
public ContextPattern appendDotStar()
```
    Return a pattern matching any context of which the current pattern matches a prefix. This is accomplished by adding the .* regular expression token.
    
    Returns:
    
    The new pattern.
  - matches
```
public ContextMatch matches(InjectionContext context)
```
    Description copied from interface: ContextMatcher
    
    Attempt to match this context matcher against the specified context. If the matcher matches, it will return a ContextMatch describing the result.
    
    Specified by:
    
    matches in interface ContextMatcher
    
    Parameters:
    
    context - The context to match.
    
    Returns:
    
    The match information, or null if the matcher does not match.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
