Method Details

getValue

InputStream getValue(IContext context,
 long start,
 long length)

Provide access to the specified range of bytes of the value. Support for partial reading is experimental, not all implementations of MendixBinary support it.

Parameters:

context - the context.

start - the beginning position.

length - the number of bytes to read.

Returns:

the stream for the requested range

Since:

8.13.0

setValue

@Deprecated
void setValue(IContext context,
 byte[] bytes)

Deprecated.

As of Mendix 8.11. Use IMendixObjectMember.setValue(IContext, Object) or IMendixObjectMember.setValue(IContext, Object, boolean) directly.

Set value to passed byte array.

retrieveValue

void retrieveValue(IContext context,
 OutputStream out)

Retrieve value and write to output stream.

storeValue

void storeValue(IContext context,
 InputStream value,
 long length)

Set the value the given input stream up to the length.

parseAndStoreValue

@Deprecated
void parseAndStoreValue(IContext context,
 String value)

Deprecated.

As of Mendix 8.11. Use IMendixObjectMember.setValue(IContext, Object) or IMendixObjectMember.setValue(IContext, Object, boolean) directly.

Set the value to the bytes in the given string.

commitValueAsFileDocument

@Deprecated
void commitValueAsFileDocument(IContext context)

Deprecated.

As of Mendix 8.11. This method is for internal use only.

Commit the current value as file document.

setLength

@Deprecated
void setLength(Long length)

Deprecated.

As of Mendix 8.11. This method should not be used.

Set the length of the value.

getLength

@Deprecated
Long getLength()

Deprecated.

As of Mendix 8.11. Use getLength(IContext) instead.

Get the length of the binary value if set previously.

getLength

Long getLength(IContext context)

Returns the length of the stored binary data. If the underlying entity has a length field then its permissions apply. If not, the permissions of the content attribute are applied.

Returns:

the length of the stored binary data or null if the length is unknown

getContentType

String getContentType(IContext context)

Return Content-Type.

Returns:

the binary's content type if known, null otherwise

getFileName

String getFileName(IContext context)

Return file name.

Returns:

the binary's file name if known, null otherwise

getETag

String getETag(IContext context)

Return ETag.

Returns:

an ETag for the binary, getETag should never return null
