# Interface: com.pnfsoftware.jeb.core.units.code.android.IDexFile Representation of a DEX entry. For dex version 40 and below, each entry is mapped to a single file \(hence the name of this class, at the time it was introduced\). For dex version 41 and above with containers, a single dex file may generate multiple dex entries. IMPORTANT\! This interface will be renamed to `IDexEntry` in a future release. ## Method: getActualChecksum - return type: `int` Description: Get the computed checksum. It may differ from the expected one. return: the actual checksum ## Method: getActualSignature - return type: `byte[]` Description: Get the computed signature. It may differ from the expected one. return: the actual SHA\-1 signature ## Method: getCallSitesPoolOffset - return type: `int` Description: Convenience method. Always return 0 for DEX files version 37\-. return: the call site pool offset ## Method: getCallSitesPoolSize - return type: `int` Description: Convenience method. Always return 0 for DEX files version 37\-. return: the call site pool size ## Method: getClassesPoolOffset - return type: `int` Description: Get the class pool offset. return: the class pool offset ## Method: getClassesPoolSize - return type: `int` Description: Get the class pool size. return: the class pool size ## Method: getData - return type: `byte[]` Description: Retrieve the bytes of the underlying `dex` file. Multiple entries may share the share byte buffer. return: the backing dex bytes ## Method: getDataSectionOffset - return type: `int` Description: Get the data section offset. return: the data section offset ## Method: getDataSectionSize - return type: `int` Description: Get the data section size. return: the data section size ## Method: getEndianness - return type: `com.pnfsoftware.jeb.util.io.Endianness` Description: Get the endianness of this file. Currently, all DEX files use a little\-endian byte ordering. return: the file endianness ## Method: getExpectedChecksum - return type: `int` Description: Get the header provided file checksum. return: the expected checksum ## Method: getExpectedFileSize - return type: `int` Description: Get the header provided expected DEX size. deprecated: use [#getExpectedSize()](#getExpectedSize()) instead return: the expected dex size ## Method: getExpectedSignature - return type: `byte[]` Description: Get the header provided SHA\-1 file signature. return: the expected SHA\-1 signature ## Method: getExpectedSize - return type: `int` Description: Get the header provided expected DEX size. return: the expected dex size ## Method: getFieldsPoolOffset - return type: `int` Description: Get the field pool offset. return: the field pool offset ## Method: getFieldsPoolSize - return type: `int` Description: Get the field pool size. return: the field pool size ## Method: getFileIndex - return type: `int` Description: The underlying dex file index. When children of an APK unit, 0 would be attributed to means `classes.dex`, 1 to `classes2.dex`, etc. return: the physical dex file index ## Method: getHeaderSize - return type: `int` Description: Get the size of header. return: the header size ## Method: getIndexInContainer - return type: `int` Description: The index of this entry in their dex container, if the corresponding physical dex file is a v41 container. The primary entry at offset 0 would have index 0, subsequent entries indices 1, 2, etc. return: the entry index in the dex container ## Method: getLinkSectionOffset - return type: `int` Description: Get the link section offset. return: the link section offset ## Method: getLinkSectionSize - return type: `int` Description: Get the link section size. return: the link section size ## Method: getMap - return type: `com.pnfsoftware.jeb.core.units.code.android.dex.IDexMap` Description: Get a map object for this file. return: the dex map ## Method: getMapOffset - return type: `int` Description: Get the map offset. return: the map offset ## Method: getMethodHandlesPoolOffset - return type: `int` Description: Convenience method. Always return 0 for DEX files version 37\-. return: the method handle pool offset ## Method: getMethodHandlesPoolSize - return type: `int` Description: Convenience method. Always return 0 for DEX files version 37\-. return: the method handle pool size ## Method: getMethodsPoolOffset - return type: `int` Description: Get the method pool offset. return: the method pool offset ## Method: getMethodsPoolSize - return type: `int` Description: Get the method pool size. return: the method pool size ## Method: getNameTag - return type: `java.lang.String` Description: Get the optional name tag associated with this dex entry. return: an optional name tag associated with the object \(usually, the file name that contained the dex file or dex container used to create this object\) ## Method: getOffset - return type: `int` Description: Offset within [data](#getData()) of the start of this dex. return: an offset, generally 0 ## Method: getOwnerUnit - return type: `com.pnfsoftware.jeb.core.units.code.android.IDexUnit` Description: Retrieve the owner DEX unit. return: the owner dex unit ## Method: getPrototypesPoolOffset - return type: `int` Description: Get the prototype pool offset. return: the prototype pool offset ## Method: getPrototypesPoolSize - return type: `int` Description: Get the prototype pool size. return: the prototype pool size ## Method: getStringsPoolOffset - return type: `int` Description: Get the string pool offset. return: the string pool offset ## Method: getStringsPoolSize - return type: `int` Description: Get the string pool size. return: the string pool size ## Method: getTypesPoolOffset - return type: `int` Description: Get the type pool offset. return: the type pool offset ## Method: getTypesPoolSize - return type: `int` Description: Get the type pool size. return: the type pool size ## Method: getVersion - return type: `int` Description: Get the DEX version number. return: the dex version number
