java.lang.Object | +--org.apache.tools.ant.types.selectors.modifiedselector.DigestAlgorithm
Computes a 'hashvalue' for the content of file using java.security.MessageDigest. Use of this algorithm doesn't require any additional nested s. Supported s are:
| name | values | description | required |
|---|---|---|---|
| algorithm.algorithm | MD5 | SHA (default provider) | name of the algorithm the provider should use | no, defaults to MD5 |
| algorithm.provider | name of the provider to use | no, defaults to null |
| Constructor Summary | |

| Method Summary | |
java.lang.String |
getValue(java.io.File file)
Computes a value for a file content with the specified digest algorithm. |
void |
initMessageDigest()
Initialize the security message digest. |
boolean |
isValid()
This algorithm doesn't need any configuration. |
