DescriptiveResource

public DescriptiveResource(String description)

Create a new DescriptiveResource.

参数:

description - the resource description

方法详细资料

exists

public boolean exists()

This implementation checks whether a File can be opened, falling back to whether an InputStream can be opened.

This will cover both directories and content resources.

指定者:

exists 在接口中 Resource

覆盖:

exists 在类中 AbstractResource

getInputStream

public InputStream getInputStream()
                           throws IOException

从接口复制的说明: InputStreamSource

Get the content of the resource as input stream.

返回:

input stream of Resource content

抛出:

IOException - If an input exception occurs

toString

public String toString()

从接口复制的说明: Resource

Return a description for this resource, to be used for error output when working with the resource.

Implementations are also encouraged to return this value from their toString method.

指定者:

toString 在接口中 Resource

覆盖:

toString 在类中 AbstractResource

另请参阅:

• Object.toString()

equals

public boolean equals(Object other)

This implementation compares the underlying description String.

覆盖:

equals 在类中 AbstractResource

hashCode

public int hashCode()

This implementation returns the hash code of the underlying description String.

覆盖:

hashCode 在类中 AbstractResource
