Method Detail

getPath

public String getPath()

Description copied from interface: Resource

Returns the normalized, ResourceAccessor-relative path for this resource. To get the unique location of this resource, use Resource.getUri() This should always use `/` for separators This should not include any sort of protocol or prefixes This should not have a leading /. This should have any relative paths smoothed out -- return "path/to/resource" not "path/from/../to/resource".

Specified by:

getPath in interface Resource

getUri

public URI getUri()

Description copied from interface: Resource

Returns a unique and complete identifier for this resource. This will be different than what is returned by Resource.getPath() because the path within the resource accessor whereas this is the a complete path to it.

For example, a file resource may return a path of my/file.txt and a uri of file:/tmp/project/liquibase/my/file.txt for a resource accessor using file:/tmp/project/liquibase as a root

Specified by:

getUri in interface Resource

isWritable

public boolean isWritable()

Description copied from interface: Resource

Return true if the resource can be written to

Specified by:

isWritable in interface Resource

openOutputStream

public OutputStream openOutputStream(OpenOptions openOptions)
                              throws IOException

Description copied from interface: Resource

Opens an output stream given the passed OpenOptions. Cannot pass a null OpenOptions value

Specified by:

openOutputStream in interface Resource

Throws:

IOException

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

resolvePath

protected String resolvePath(String other)

Convenience method for computing the relative path in Resource.resolve(String) implementations

resolveSiblingPath

protected String resolveSiblingPath(String other)
