## Implements

## Methods

### getHeaderName()

    public abstract String getHeaderName()

Required. The name of the HTTP header to match. For matching
against the HTTP request's authority, use a headerMatch
with the header name ":authority". For matching a
request's method, use the headerName ":method".

`string header_name = 1 [(.google.api.field_behavior) = REQUIRED];`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://docs.oracle.com/javase/8/docs/api/java/lang/String.html` | The headerName. |

### getHeaderNameBytes()

    public abstract ByteString getHeaderNameBytes()

Required. The name of the HTTP header to match. For matching
against the HTTP request's authority, use a headerMatch
with the header name ":authority". For matching a
request's method, use the headerName ":method".

`string header_name = 1 [(.google.api.field_behavior) = REQUIRED];`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://cloud.google.com/java/docs/reference/protobuf/latest/com.google.protobuf.ByteString.html` | The bytes for headerName. |

### getRegexMatch()

    public abstract String getRegexMatch()

Required. The value of the header must match the regular expression
specified in regexMatch. For regular expression grammar,
please see: en.cppreference.com/w/cpp/regex/ecmascript
For matching against a port specified in the HTTP
request, use a headerMatch with headerName set to Host
and a regular expression that satisfies the RFC2616 Host
header's port specifier.

`string regex_match = 2 [(.google.api.field_behavior) = REQUIRED];`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://docs.oracle.com/javase/8/docs/api/java/lang/String.html` | The regexMatch. |

### getRegexMatchBytes()

    public abstract ByteString getRegexMatchBytes()

Required. The value of the header must match the regular expression
specified in regexMatch. For regular expression grammar,
please see: en.cppreference.com/w/cpp/regex/ecmascript
For matching against a port specified in the HTTP
request, use a headerMatch with headerName set to Host

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://cloud.google.com/java/docs/reference/protobuf/latest/com.google.protobuf.ByteString.html` | The bytes for regexMatch. |

### getTypeCase()

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://docs.cloud.google.com/java/docs/reference/google-cloud-network-security/latest/com.google.cloud.networksecurity.v1.AuthorizationPolicy.Rule.Destination.HttpHeaderMatch.TypeCase` |   |

### hasRegexMatch()

    public abstract boolean hasRegexMatch()

Required. The value of the header must match the regular expression
specified in regexMatch. For regular expression grammar,
please see: en.cppreference.com/w/cpp/regex/ecmascript
For matching against a port specified in the HTTP
request, use a headerMatch with headerName set to Host
and a regular expression that satisfies the RFC2616 Host
header's port specifier.

`string regex_match = 2 [(.google.api.field_behavior) = REQUIRED];`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html` | Whether the regexMatch field is set. |
